Answer:
The percent by mass of 3.55 g NaCl dissolved in 88 g water is 3.88%
Explanation:
When a solute dissolves in a solvent, the mass of the resulting solution is a sum of the mass of the solute and the solvent.
A percentage is a way of expressing a quantity as a fraction of 100. In this case, the percentage by mass of a solution is the number of grams of solute per 100 grams of solution and can be represented mathematically as:
[tex]Percent by mass=\frac{mass of solute}{mass of solution} *100[/tex]
In this way it allows to precisely establish the concentration of solutions and express them in terms of percentages.
In this case:
Replacing:
[tex]Percentbymass=\frac{3.55}{91.55}*100[/tex]
Percent by mass= 3.88%
The percent by mass of 3.55 g NaCl dissolved in 88 g water is 3.88%
The percent by mass of 3.55 g NaCl dissolved in 88 g water will be:
"3.88%".
A unit of measurement for the quantity of solute absorbed or saturated throughout a given proportion of solvent as well as solutions. A concentrated solution contains a significant proportion of absorbed components.
According to the question,
Mass of solute = 3.55 g
Mass of water = 88 g
Mass of solution = 3.55 + 88
= 91.55 g
We know the formula,
→ Percent by mass = [tex]\frac{Mass \ of \ solute}{Mass \ of \ solution}[/tex] × 100
By substituting the values, we get
= [tex]\frac{3.55}{91.55}[/tex] × 100
= 3.88 %
Thus the answer above is correct.
